Vulnerability assessment for mining subsidence hazard

Abstract : After the last mining subsidence events, which occurred in the iron-ore field in Lorraine (France) in 1996, 1997 and 1999, and because of the thousand hectares of undermined areas, the assessment of vulnerability of buildings and territories became necessary for risk management. The ten last years highlight evolutions of the vulnerability concept and its assessment method between the first risk management decisions and current risk assessment. These evolutions reveal a lot about the complexity of the vulnerability concept and about difficulties to develop simple and relevant methods for its assessment. The objective of this paper is to present this evolution and to suggest different improvements compared to other concepts and methods developed in other countries (USA, Poland...) and for other hazards (flood, industrial...). These improvements take into account more various kinds of elements in the vulnerability meaning (buildings, people, roads, public facilities and public functions) as well as they deal with method of assessment in relation to the subsidence intensity and vulnerable elements.
